Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of 2-diethylaminoethanol (CAS 100-37-8) was determined in a GLP guideline study according to OECD 301A (BASF AG, 2002) using domestic activated sludge as inoculum. The test substance was determined to be readily biodegradable after 28 d (ten day window was met; 82% based on BOD after 10 d).
The key data are supported by the results of an inherent biodegradability test according to OECD TG 302 B (Zahn-Wellens/EMPA Test) with domestic activated sludge as inoculum; biodegradation of the substance was 96% after 14 d, based on BOD (BASF AG, 1994).
In addition, Eide-Haugmo et al. (2012/2009) performed two guideline studies according to OECD 306 using natural seawater as inoculum. The chemical turned out to be poorly biodegradable under marine conditions (<5% O2 -consumption after 28 d).
In conclusion, the substance is readily biodegradable (according to OECD criteria).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
